LDWF requires that wholesale/retail seafood dealers and wholesale/retail reptile and amphibian dealers purchasing or accepting transfers of catch from commercial fishermen or reptile/amphibian collectors submit trip tickets to capture information about the catch—what it is, where it was caught, how it was caught, and how much was caught. Fresh products license holders (commercial fishermen licensed to sell their catch directly to consumers) are also required to submit trip tickets. LDWF uses this information to improve assessments of fish populations and inform management.
Waterbody Management Plans
To monitor our freshwater finfish resources, LDWF biologists routinely sample rivers, streams, lakes and reservoirs based on their importance to the fishing public, size, productivity, and, in the case of reservoirs, drawdown capability. They take thousands of samples, using various sampling methods including electrofishing, seines, gillnets, hoop nets, and lead nets to evaluate the composition and abundance of Louisiana’s freshwater finfish species. They also collect water quality data with every sample to assess dissolved oxygen, pH, salinity and conductivity. Monitoring and management results are reported in Waterbody Management Plans.
